Our history

The companies that have resourced the Group combine over a century of experience in the pharmaceutical industry, and have all been highly innovative in addressing the changing needs of both the company and patients.

Sanofi is the heir to a long history that includes some of the major scientific advances of the nineteenth and twentieth centuries, and the reputations of major industrial laboratories in the development of chemistry, pharmacy and medicine.

In 1863, a group of chemists, sales people and workers embarked on the manufacture of dyes in a small factory to the west of the town of Höchst in Germany. This was the origin of the company Hoechst, which merged with Roussel (founded in 1911) to form Hoechst Marion Roussel.
